As shown in Figure 1, the SPE uses one 1.2-kilowatt SPS to maintain power to the storage system during a power loss to allow for a full dump of the write cache to a reserved area on persistent disk. An additional SPS can be added for further redundancy
When only one SPS is used, the power output connectors for the SPS supply power to SP A and the first DAE on the first back-end loop. The power for SP B and the remaining power to the first DAE on the first back-end loop are supplied by the PDU within the CLARiiON 40U rack. When two SPSs are used, the power output connectors from the additional SPS power both SP B and the first DAE.

It is important to cable each SPS so it connects completely to either the A side or the B side. For example, if you are looking at the SPS from the back, they should be configured as follows:
- SPS on the right: Power-out and sense cables should connect to power supply A and SP A.
- SPS on the left: Power-out and sense cables should connect to power supply B and SP B (optional).
If an SPS is cabled with the SPS sense cable going to SP A and the power-out cable going to power supply B (or vice versa), error conditions are displayed when the SPS is tested while it is charging.
Finding a replacement for our EMC VNX was very difficult. A good number of places that list the part on their website, but this was the only place that actually had it in stock.
